What is the mass of a crate if a force of 200 N causes it to accelerate at 8 m/s²? (Formula: [tex]F = ma[/tex])

A. 25 kg
B. 192 kg
C. 208 kg
D. 16 kg

Answer :

We start with Newton's second law of motion, which relates force, mass, and acceleration by the equation

[tex]$$ F = m \times a. $$[/tex]

In this problem, the force [tex]$F$[/tex] is given as [tex]$200\,\text{N}$[/tex] and the acceleration [tex]$a$[/tex] is given as [tex]$8\,\text{m/s}^2$[/tex]. We need to find the mass [tex]$m$[/tex].

To do this, we rearrange the equation to solve for [tex]$m$[/tex]:

[tex]$$ m = \frac{F}{a}. $$[/tex]

Substitute the given values into the formula:

[tex]$$ m = \frac{200}{8}. $$[/tex]

Performing the division:

[tex]$$ m = 25\,\text{kg}. $$[/tex]

Thus, the mass of the crate is [tex]$25\,\text{kg}$[/tex].
